Great news. There is another version of Armbian that is based on Ubuntu that also works on the Rockpi 4. It's called TwisterOS. It gives you the ability to simply use the stable or bleeding edge version of Kstars/Ekos by simply adding the ppa. You can get TwisterOS or the RockPi from here: twisteros.com/twisterarmbian.html Its best to use the mirror link on this site as the host site is VERY slow.
